What is the difference between aluminum extrusion vs aluminum die casting?
In the field of industrial manufacturing, aluminum has become the material of choice in the automotive, electronics, and construction industries due to its lightweight, corrosion-resistant, and high-strength characteristics. However, the core difference between the two processes of aluminum extrusion (Aluminum Extrusion) and aluminum die casting (Aluminum Die Casting) directly affects the production cost, structural accuracy and mass production efficiency. As a deep ploughing aluminum die casting field 20 years of technical experts, ningbo he Xin die casting factory through this paper analysis of the engineering logic of the two processes, and share how to through the precision die casting technology for customers to reduce costs and increase efficiency. Forming principle of the essence of the contrast (the fundamental difference between the way the material flow) aluminum extrusion process through up to 15000 tons of hydraulic pressure, forcing the ingot heated to 400-500 ℃ through the hole of the special mold, this continuous plastic deformation process similar to the "toothpaste squeeze"...

ADC12 Die-Cast Aluminum Alloy Comprehensive Guide: Compositional Properties, Mechanical Properties and Industry Applications
ADC12 (Japan JIS standard 12 aluminum) is a high-performance Al-Si-Cu die-cast aluminum alloy, which implements the JIS H 5302-2000 standard. The alloy is known for its excellent casting fluidity, good machinability and high dimensional stability, and is particularly suitable for the production of complex thin-walled components. Its typical composition (Si 9.6-12.0%, Cu 1.5-3.5%) ensures that the material combines good strength, heat and corrosion resistance while keeping production costs low. In the automotive industry, ADC12 is widely used in the manufacture of key components, including cylinder head covers, various types of sensor housings, engine mounts, transmission components and motor housings and other structural parts. It is one of the most common materials used in the die casting industry. Material Composition JIS Standard CuSiMgZnFeMnNiSnAl ADC121.5-3.59...

Die-casting aluminum alloy ADC12 products shot blasting skinning reason analysis and solution recommendation
This article systematically analyzes the correlation between the material properties of die-casting aluminum alloy ADC12 and shot blasting process, and puts forward a multi-dimensional solution for the frequent shot blasting peeling problem in the industry. The article firstly elucidates the direct influence of ADC12 chemical composition on material properties, revealing the intrinsic correlation between fluctuations in the content of silicon, copper, magnesium and other elements and the fluidity, strength and corrosion resistance of the alloy. Based on the principle of shot peening process, the article analyzes the quantitative role of core variables such as shot parameters and ejection speed on the surface treatment effect, and points out that there is a common shortcoming in the current industry that only focuses on adhesion but ignores the standardization of surface quality. Through mold flow analysis, process parameter optimization and experimental verification, we innovatively constructed a whole chain improvement system from material source control to mold design and equipment maintenance, and combined with the case of electric motor shell, we demonstrated the optimization of exhaust channel, storage...

Chrome-free surface passivation for aluminum alloys
Applications of Aluminum Aluminum is the most productive and widely used metallic material among non-ferrous metals. It is second only to steel in terms of production of structural metallic materials. All-aluminum engines The advantage of cast aluminum blocks in die-casting production is their light weight, which enables fuel savings through weight reduction. In an engine of the same displacement, the use of an aluminum block engine reduces weight by about 20 kilograms. For every 10% reduction in the car's own weight, fuel consumption can be reduced by 6% to 8%. Disadvantages of chromate surface treatment The waste tank liquid of chromate treatment method contains a large amount of hexavalent chromium ions, and according to GB 8978--1996 Comprehensive Sewage Discharge Standard, the concentration of hexavalent chromium in the waste tank liquid is not more than 0.5mg/L. However, hexavalent chromium ions have carcinogenic effect on human body. Long-term exposure to hexavalent chromium compounds can lead to...

Casting vs. machining: how do we choose?
As a core member of Ningbo Hersin's casting technology team, I have been working in the field of high pressure casting, low pressure casting, gravity casting and aluminum materials for more than 20 years, and have led the process development of hundreds of industrial projects. Whenever a customer raises the question of "how to choose between casting and machining", my answer is always: "There is no absolute advantage or disadvantage, only the most suitable combination of technologies for the scene." The following technical principles, practical experience and industry trends in three dimensions, in-depth analysis of the core differences between the two and the logic of choice. What is casting? Casting is melting metal, manufacturing casting, and pouring molten metal into the casting, solidification to obtain a certain shape and performance of the casting molding method. Casting and other parts molding process, compared with low production costs, process flexibility, almost independent of the size and shape of the part...
